- tral plane of d, parallel with the s-lngs radial; plane, and these surfaces alternate with surfaces parallel With the radial plane ofthe adjacent slug. The surfaces 4- parallel With the cen the slug itself on oneside are opposite the inclined surfaces 3 on the opposite side. Similarly, the surfaces 2 parallel with thecentral plane are opposite the snrfaces This is clearly illustrated in Fig. 6. lt -will be noted also that the ribs and grooves are ef substantially the same Width runningivise of the type.

Fig. 7 shows the type bodies on an enlarged scale and the direct-ions of their side planes with reference to the center of 'the drum for 'which they are designed. F ive type bodies `are shown indicated by la, l, lc, ld and le respectively. Consider' for eaainple the second type body from the right,

lh; its ribs 2 and et are parallel, as shown by the lines i and E which continue in the planes of these ribs until tangent to a construction circle C, the diameter of which is equal to the width of the 'type body. The bottom of the grooves I3 on the right hand side of the type body l" are in a plane indicated by D, which is tangent to the left Side of the circle C While the bottom of the grooves 5 on the left side-of the body lb are in a plane, indicated by E. which is tangent to the right side of the circle (la `l`-low as 'the circle has a diameter equal to the 4h of the typef-the radinswis of cour-se equal to half the Width so that a plane through the center of the circle C and the center of the typt-)betty la (that'is a radial plane E) will vbe distant half the Width of a type from thev plane D, and hence be parallel therewith. Similarly the radial plane G of the type body l" is parallel with the plane E. This shows that one portion of each side of a type bar parallel with the central plane of tliebody itself, and the other portion of each side is 'parallel with the central plane of the adjacent body.

instead of considering the characteristics of a type body with reference to the adjacent bodv as in the above explanation, these characterxstics may be defined in terms of the type body itself and the radius of the drum 'on which they are designed toseat. ".Qhus, referring to the type ld in Fig, 7, the plane of the face of the ribs i), (the plane fr) tangent to the central circle C at the right hand side of the center, While the plane D, delining the bottoni or face of the groove 3, is tangent to th same circle on the other e. Therefore, a radialplane from the center of "the drinn to the intersection of the planes A and D (that is, to the outer corner of the type body) must bi-sect they angle of those planes at all points be `ii-:ilistance therefrom. i? rom this it foltl at the face of the 'ooves stands bach he plane of ri s any poizrfL twice the distance the radial plane through the outer corner of the 'type body stands back from such plane of the rib face.

The above dened characteristics may be conveniently put in algebraic form. Referring to Fig. 7, let la indicate the distance from the central plane of the type body to either1 of the planes bounding the sides; that is, to What' may be called the rib plane, and let R indicate the radius of the drum. These factors are constant for any particular type body. Now, let t indicate any portion of the height ofthe type from the bottom up and 151 Now, by similar triangles, the distance at the outer end of the type body between the central plane and the outer c'orner (le) must bear the same ratio to y at any point in the height of the type (that is the point between t and 251) as the distance from the outer corner of the type to the center of the drum is to the distance 'from the selected point of measurement for y to the center of the drinn. Therefore,

+R y (MLHR Non', substitute y in the above formula of :erh/Mk, We have l .li E* kilwrwr) T his gives us, therefore, the depth or the distance from anyv point in the face of the groove to the central plane of the type in terms of the height and thickness of the type and the radius of the drum.

7 represents the character on the edge of the body, which may be cameo or intaglio orfplanographic, according to the Werl: to be done.

8 and 9 represent notches formed in the opposite ends of a type slug, which provide means for receiving a'snitable flange to hold them in place on a drum. It is to be under stood thatthese notches are illustrative of any suitable holding means.
